这段代码意味着什么：`$ Odd =（$ Odd ==“even”）？ “奇怪”：“偶数”;`？

Question

<?php
$Odd = "even";
$query = $MySQLi->query("SELECT id, look, username, motto FROM users WHERE rank =     '7'");
if($query->num_rows > 0):
while($UserRow = $query->fetch_assoc())
{
    $Odd = ($Odd == "even") ? "odd" : "even";
?>

I'm using a CMS for some web. But I don't really understand this code exactly, especially this line:

$Odd = ($Odd == "even") ? "odd" : "even";

Can you guys help me?

Answer 1

$Odd = ($Odd == "even") ? "odd" : "even";

means

if($Odd == "even") {
    $Odd = "odd";
}
else {
    $Odd = "even";
}
